IMPROVED MODE OF HANG-ING VVINDOVV'-CURTAJIINS.`

The Schedule referred toin these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, HENRY AIKEN, of Philadelphia, in the county of Philadelphia, and State of Pennsylvania, have invented new and useful Improvements in Hanging Window-Curtains; and I do hereby declare that the following is a full, clear,l and exact description thereof, eference being had to the annexed drawings, making part of this specicat-iomin which- Figure 1 represents a front elevation, and

Figure 2 representspa central vertical section.

The same letters are used in both figures to designate identical parts.

My invention consists in so arranging a windowcurtain or blind, in connection with rollers, pulleys, and two endless cords or bands, that it may be lowered from the top or raised from the bottom by means of said cords, or bands, the arrangement bein'g such that the roll around which lthe curtain yis wound has a positive movement vertically, which Inoven'ient is controlled by Vsuch cords onbands, as will be vmore fully described hereinafter. y

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation. 's

A, in the drawings,- represents a window-sash or frame, in which a curtain is to be hung.

.This curtain bis provided, at both its lower and upper ends, wit-h rolls B and B', upon eitheror both of which it can be wound. i

Each roll has formed .upon one of its projectingends two separat-e grooves, in one of which the endless cords work, for giving a vertical movement to the respective roll, and the other one receives the fixed cords, which form bearings for the rolls, andalso'im? part to them a rotary motion while being l'uoved vertically. The opposite ends of the rolls `are provided with only one groove for the reception of the vfixed cords. The arrangement-of the rolls, with reference to each other, being such that their double grooved ends are at opposite sides'of the curtain, that is, if the upper roll has the two grooves at the right ofthe curtain, as shown in the drawings, the lower roll is to be so attachedto the curtain that its double grooved end is at the left thereof.

C G represent the fixed-cords, the upper ends of which are secured in the upper corners of the frame, in any convenient manner; thence passing downward, they are wound once around the respective grooved ends of' the upper roll, holding it/in a horizontal position, and again descending, they are wound 4in the same manner around the lower roll, the curtain being kept taut at this time,'when ltheir lower ends are extended to the lower corners of the sash, and. there conveniently secured.

D D' represent two endless cords. The one I have denominated D is to operate, in this instance, the lower roll B', while the other one, D', is to give motion to the upper roll B.

Each cord is arranged upon pulleys E E, which revolve upon studs respectively secured at top and bottom of the window-frame.

By reference to the drawings, it will be seen that the inner side of the cord D is wound once around the double grooved end of the lower roll B', so that as the former is moved in one direction or the other, it will raise or lower the latter. At the same time the cords C C will cause the roll to revolve around its axis, so as to wind the curtain up, or unwind it, as the case may be. The endless cord Dis arranged in like manner with reference to the upper roll B.

It will be observed that the endless cords are wound around the respective rolls in an opposite direction from the fixed cords, whereby the rolls are prevented from slipping.

f From the above-described arrangement, it will be apparent that by operating the endless cords, a positive movement, vertically, is imparted to the rolls, independent of gravity, thereby dispensing with weighted rollers or tassels. At the same time the arrangement of the parts is so simple, that when properly put up they cannot get out of order.

Having thus described my invention,

What I claim, and desire to secure by Letters 'Patent, is-

1. Arranging a window-curtain, iu connection with rollers and pulleys, with two endless cords, whereby it may be lowered from the top, or raised from the bottom, and two fixed cords for rotating the rolls ns theyl are moved vertically, substantially as set forth.

2. The combination of the rolls B B', fixedcords (l C', endless cords D D', and pulleys E,'all arranged to operate substantially as and for the purpose set forth.

In testimony' whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

HENRY AlKEN.
